Video Description
Bugs are inevitable, but finding them doesn't have to be painful! Learn essential debugging techniques that will save you hours of frustration.
What you'll learn: • Reading error messages (they're trying to help you!) • Common C# error messages decoded • Console.WriteLine debugging - the classic approach • Strategic placement of debug output • Setting breakpoints in VS Code • Step through, step over, step into explained • Watch windows and variable inspection • Conditional breakpoints for tricky bugs • The systematic bug-finding process • Why your breakpoint might not be hitting
Key debugging wisdom: • Error messages point you to the problem • Start with the simplest debugging technique • Breakpoints let you watch your code execute • Debugging is how you truly learn what your code does
Common mistakes we'll fix: • NullReferenceException (the #1 C# error) • "Does not exist in the current context" • Index out of bounds • Build vs runtime errors
